To all 'who/a it'mag/ concern:

Be it known that I, CHRISTOPHER F. CODA, a citizen of the United States of America, residing at etroit, in the county of IVayne and State of Michigan, have invented certain new and useful Improvements'in Combination-Ranges, of which the following is a specilication, reference being had therein to the accompanying drawings.

Wy invention relates to combination ranges, and resides in the provision of an adjustable burner; in the provision of an adjustable shield for the burner; in the mechanism for adjusting the shield and the burner; in the manner of controlling the air damper for the oven; and in certain relations and combinations of parts and details of construction as will more fully hereinafter appear.

In the drawings,-

Figure l is a sectional side elevation through a range with my improvement applied thereto;

Fig. 2 is a sectional front elevation; and

Fig. 3 is a sectional plan' view.

A designates a combination range, B the fire-box thereof. C is the oven and D the flue leading around the oven to the back flue E in the usual manner. These parts may be of any suitable construction.

In combination ranges the oven is adapted to be heated either by employing solid fuel or by means of a gas burner arranged in suitable relation to the oven. In construe tions now in quite common use, when the gas burner is employed a shield of substantially the same size as the oven bottom is employed, but when the oven is heated by solid fuel, this shield is removed by hand. I have devised a novel arrangement of shield and burner Which Will permit both the shield and the burner When not in use to be readily moved to a stored position. Referring to the one embodiment of the invention shown in the drawings, the gas burner has a section F that extends diagonally inward from the rear outer corner of the oven, and the burnel` has second section G formed integral With the section F and extending through lthe oven side Wall I-I to Without the oven. This section G is free to turn Within the opening in the side Wall H, and in effect forms a pivot or axis about Which the'section F may be turned. I is the shield for the oven burner Which is shown as of a sine but slightly less in area than the oven bottom. The shield I is supported at its forward end `by means of legs J and is pivoted at one side as indica-ted at K Within a bearing L in the inner side Wall M of the oven. rIhe burner is rigidly connected to the shield and therefore the portion G forms the pivot for Ythe opposite' side of the shield'. In the structure shown the burner has ears a which are bolted to the shield. i

By the arrangement described, when the oven is to beheated by solid fuel, the gas burner and shield may he turned into the position shown in dotted lines in Fig. I, and as will be noted,in this `position both the shield and the burner lie in close proximity to the back Wall of the oven and therefore do not materially restrict or interfere With the capacity of the oven.

lith the construction shown, the shield is (zi-'greater length than the heightof the rear wall of the oven. I therefore form the shield in two sections and hingedly connect these sectionsl together, as indicated at O. The hinge connection is such that when the shield is raised, it will permit theouter' section P to fold into parallelism With the larger or inner section Q of the shield, but When the shield is in use the hinge connection Will maintain the parts in alinement, as shown in Fig. l.

Preferably I provide means for moving the shield and burner into and out of operative position. In the structure illustrated the section G of the burner has rigidly attached thereto an arm R which is pivotally connected at S to a link T. The latter member is in turn pivotally connected at U to a lever IV that is fulcrumed at X upon a pin Y carried by a. bracket Z attached to the side Wall A of the oven. The arrangement of parts is such that When the hand lever W is moved to the position shown in full lines in Fig. 1, the shield and burner Will be in operative relation to the oven, While when moved to the position shown in dotted lines, the shield and burner Will be retained in close proximity to the back Wall of the oven. This forms a very convenient arrangement, and not only avoids removing the shield from the oven,

but allows the converting of the oven from one adapted to be heated by gas to one adapted to be heated by solid fuel, not only to'be very easily effected but also to be accomplished from without the oven.

It is usual to provide a supply of air for the oven when it is heated by gas, so as to permit the proper burning of the gas. I have devised a construction in which the air supply opening will be automatically closed when the burner is moved to inoperative position and will be automatically opened when the burner is in operative position. Referring to the particular structure shown in the drawing, B is an air supply chamber below the oven bottoni and C is an opening in the oven bottom communicating with this air chamber. D is a damper pivoted at E to a bracket Il". This damper when the burner is moved to an inoperative position is held closed by means of a gravity dog G. This dog is pivoted at H to a suitable support I and has a weight-ed end J which tends to raise the opposite end K of the dog. The end K engages the damper D and tends to hold the damper in its closed position, the end J being of suicient weight to overcome the weight of the member D. To open the damper the burner is provided with a down wardly-extending lug L which when the burn-er is moved to operative position will press down upon the damper D and because of the greater weight of the burner and shield, will move the damper to open position against the weight of the dog G. The oven is provided with the usual air outlet openings adjacent the top thereof, as indicated at M.

l/Vhile I have shown and described one particular form of the invention, and although this particular embodiment is highly desirable, I do not wish to limit the protection to the particular structure illustrated.

Wvhat I claim as my invention is:

1. In a combination range, the combination with an oven having an air supply opening in its bottom, of a downwardly opening damper controlling said opening, means arranged beneath the oven bottom for holding said damper normally closed, a burner within the oven movable to inoperative position, and means associated with said burner for opening the damper upon displacement of the burner to its position of use.

Q. In a combination range, the combination with an oven, of a burner therewithin movable to inoperative position, an air supply opening in the oven, a damper controlling said opening, means engageable with the damper when the burner is moved to operative position for opening said damper, and means independent of the last-mentioned means for automatically closing the damperupon displacement of the. burner from its normal position.

In testimony whereof I aliiX my signature in presence of two witnesses.
